Theories of Development
Chapter Preview
A developmental theory provides a framework of ideas that permits a cohesive view of
development, produces new hypotheses to test, generates discoveries, and offers practical
guidance. This chapter describes and evaluates five broad theories—psychoanalytic theory,
behaviorism, cognitive theory, sociocultural theory, and universal theory (humanism and
evolutionary theory)—that will be used throughout the book to present information and to
provide a framework for interpreting events and issues in human development. Because
each theory emphasizes a different aspect of development and is, in itself, too restricted to
explain the diverse ways in which development occurs, the theories may be said to complement one another.
Three of the theories presented—psychoanalytic theories, behaviorism, and cognitive
theories—are “grand theories” that are comprehensive in scope but inadequate in the face
of more recent research findings. Three newer theories of development—sociocultural,
humanistic, and evolutionary—are also discussed.
Each theory has contributed to our understanding of development. Psychoanalytic theory has helped to focus attention on the importance of early experiences and potential conflicts in daily life. Behaviorism has increased awareness of the ways in which the environment influences development. Cognitive theory has broadened our understanding of how
thinking influences behavior. Sociocultural theory has reminded us that development is
embedded in a rich and multifaceted cultural context; and universal theory has called
attention to the fact that all humans are basically alike.
Most developmentalists today have adopted an eclectic perspective. In other words,
they apply insights gleaned from various theoretical views rather than limiting themselves
to only one school of thought.

1. A developmental theory is a statement of principles and generalizations that provides a coherent framework for understanding how and why people change as they
grow older.
2. Developmental theories produce hypotheses, generate discoveries, and offer practical
guidance.
3. Five developmental theories are discussed in this chapter: psychoanalytic, behaviorist,
cognitive, sociocultural, and universal. Each theory interprets human development
from a distinct perspective, and each provides guidance for understanding how human
experiences and behaviors change over time.

Grand Theories
Instructional Objective: To describe the basic concepts of the grand theories of development: psychoanalytic theory, behaviorism, and cognitive theory.
➤ Classroom Activity: “Development” as a Social Construction

➤ “On Your Own” Activity: Freud’s Influence on Psychology and American Culture
1. Psychoanalytic theory interprets human development in terms of inner drives and
motives, many of which are irrational and unconscious.
2. According to Sigmund Freud, development in the first six years progresses through
three stages; at each stage, sexual interest and pleasure are focused on a particular
part of the body—the mouth during infancy (the oral stage), the anus during early
childhood (the anal stage), and the genitalia later in the preschool years (the phallic
stage). Following a period of sexual latency, the adolescent enters the fourth stage, the
genital stage, which lasts throughout adulthood.
3. Freud believed that each stage has its own potential conflicts and that how the child
experiences and resolves the conflicts, especially during the first three stages, determines personality patterns throughout life.
4. According to Freud, the personality has three parts: the id (unconscious drives), the
superego (the conscience), and the ego (the conscious self).
5. In his theory of human development, Erik Erikson proposed eight developmental
stages, each of which is characterized by a particular challenging developmental
crisis. Erikson emphasized each person’s relationship to the social environment and
the importance of family and cultural influences in determining how well prepared
individuals are to meet these crises. Erikson’s stages are lifelong.

6. Instead of advancing a stage theory of development, proponents of behaviorism (also
called learning theory) have formulated laws of behavior that operate at every age.
The basis of all varieties of behaviorism is the idea that psychology should focus on
the objective and scientific study of behavior.
7. According to behaviorism, conditioning is the process by which responses become
linked to particular stimuli. As demonstrated by the Russian scientist Ivan Pavlov,
classical conditioning (also called respondent conditioning) involves learning by
association: The organism comes to associate a neutral stimulus with a meaningful
one.
8. In operant conditioning (also called instrumental conditioning), proposed by
B. F. Skinner, the individual learns that a particular action produces a particular
consequence.
9. Any consequence that follows a behavior and makes the person (or animal) likely to
repeat that behavior is called reinforcement.
10. Social learning theory emphasizes the ways in which people learn new behaviors by
observing and imitating, or modeling, the behavior of other people they consider
admirable, powerful, nurturing, or similar. Modeling is most likely to occur when
the observer is uncertain or inexperienced. Social learning is connected to perceptions
and interpretations of experience, and to self-efficacy.
11. (text and Thinking Critically) Both behaviorism and psychoanalytic theory have led to
hypotheses that were examined in thousands of experiments. For example, in the
1950s, researcher Harry Harlow investigated the origins of attachment in infant

monkeys. These studies, which demonstrated that infant monkeys clung more often to
“surrogate” mothers that provided contact comfort, disproved behaviorism’s view that
reinforcement was most important and psychoanalytic theory’s concept of the mother
satisfying the infant’s oral needs.

12. Cognitive theory focuses on the structure and development of thought processes and
their effect on attitudes, beliefs, and behaviors. An offshoot of cognitive theory is the
concept of information processing, which focuses on the step-by-step process of
intellectual development.
13. Jean Piaget viewed cognitive development as a process that follows a universal
sequence of age-related periods: sensorimotor, preoperational, concrete operational, and
formal operational.
14. According to Piaget, each person strives for cognitive equilibrium—that is, a state
of mental balance achieved through the development of mental concepts that explain
his or her experiences. Cognitive disequilibrium (a state of imbalance) promotes a
search for knowledge as the person modifies old concepts and constructs better ones to
fit new experiences.
15. According to Piaget, people adapt to new experiences either by reinterpreting them to
fit into, or assimilate with, old ideas. Some new experiences force people to revamp
old ideas so that they can accommodate new experiences.
16. Each grand theory has a different focus: emotions (psychoanalytic theory), actions
(behaviorism), and thoughts (cognitive theory). Each also reaches different
conclusions.
III. Newer Theories
Instructional Objective: To highlight the basic themes of the newer theories: sociocultural
theory, humanism, and evolutionary theory.

➤ Internet Activity: High-Quality Preschool Education: What Would Vygotsky Say?
1. Sociocultural theory seeks to explain human development in terms of the guidance,
support, and structure provided by cultures and societies. Rather than considering the
individual in isolation, sociocultural theorists focus on the dynamic interaction
between developing persons and the surrounding social and cultural forces.
2. Russian psychologist Lev Vygotsky, a major pioneer of the sociocultural perspective,
believed that the development of cognitive competencies results from social interaction
between children and more skilled members of the community in what has been called
an apprenticeship in thinking. The basis of this apprenticeship is guided participation, in which a skilled tutor or mentor engages the learner in joint activities.
3. In sociocultural theory, a child’s social partners progressively challenge the child’s
ever-shifting abilities and motivation. To do so, the mentor draws the child into the
zone of proximal development, which is the range of skills that the child can exercise only with assistance.

➤ “On Your Own” Activity: Introducing Evolutionary Psychology
4. The universal perspective centers on the shared impulses and common needs of all of
humanity. One universal theory is humanism. Maslow believed that all humans have
five basic needs, which he arranged in a hierarchy, beginning with survival and ending with self-actualization. Rogers believed that each person deserves respect, appreciation, and unconditional positive regard.
5. The recent application of evolutionary theory to human development emphasizes two
long-standing and biologically based needs: survival and reproduction. Current
humans react in ways that helped survival and reproduction millions of years ago
because of selective adaptation, a process essential to evolutionary theory.
6. One controversial idea stemming from evolutionary theory is that women and men are
selected for different patterns of mating and sexual behavior. According to this argument, women benefit by seeking a soul mate, while men need women to be sexually
faithful. Critics of this idea contend that a sexist upbringing rather than genes
accounts for these differences.
IV.
What Theories Contribute
Instructional Objective: To help students understand the goal of developmental theory
and that all the major theories of human development work together to provide the most
complete explanation of human development.

1.
The five theories complement one another, as each emphasizes a somewhat different
aspect of development.
(a) Psychoanalytic theory has drawn attention to the importance of early-childhood
experiences.
(b) Behaviorism has highlighted the effect of the immediate environment on learning.
(c) Cognitive theory has led to a greater understanding of how intellectual processes
and thinking affect every aspect of development.
(d) Sociocultural theory has reminded us that development is embedded in a rich and
multifaceted cultural context.
(e) Universal theories emphasize that human differences are less significant than
what all humans share.
2.
Each theory has faced criticism: psychoanalytic theory, for being too subjective; behaviorism, for being too mechanistic; cognitive theory, for undervaluing emotions; sociocultural theory, for neglecting individuals; and universal theory, for slighting cultural,
gender, and economic variations.
3.
Today, most developmentalists have an eclectic perspective. Instead of limiting
themselves to only one school of thought, they apply insights drawn from various
theoretical views.
